Perform the following tests according to TIA/EIA-568-D.1 and TIA/EIA-568-C.2: 1) Wire map. 2) Length (physical vs. electrical, and length requirements). 3) Insertion loss. 4) Near-end crosstalk (NEXT) loss. 5) Power sum near-end crosstalk (PSNEXT) loss. 6) Equal-level far-end crosstalk (ELFEXT). 7) Power sum equal-level far-end crosstalk (PSELFEXT). 8) Return loss. 9) Propagation delay. 10) Delay skew. 7. Optical Fiber Cable Performance Tests: Perform optical fiber end-toend link tests according to TIA/EIA-568-C.1 and TIA/EIA-568-C.3. 8. Coaxial Cable Tests: Conduct tests according to Section 274133 "Master Antenna Television System." 9. Final Verification Tests: Perform verification tests for UTP and optical fiber systems after the complete communications cabling and workstation outlet/connectors are installed. a. Voice Tests: These tests assume that dial tone service has been installed. Connect to the network interface device at the demarcation point. Go off-hook and listen and receive a dial tone. If a test number is available, make and receive a local, long distance, and digital subscription line telephone call. b. Data Tests: These tests assume the Information Technology Staff has a network installed and is available to assist with testing. Connect to the network interface device at the demarcation point. Log onto the network to ensure proper connection to the network. B. Document data for each measurement. Data for submittals shall be printed in a summary report that is formatted similar to Table 10.1 in BICSI TDMM, or transferred from the instrument to the computer, saved as text files, and printed and submitted. C. End-to-end cabling will be considered defective if it does not pass tests and inspections. D. Prepare test and inspection reports. 3.8 WARRANTY A. Contractor shall provide a Manufacturer s Warranty covering all Copper and Fiber Optic Cabling and Connecting Components. 1. Materials shall be covered for no-less than twenty (20) years from date of substantial completion of this work. 27 15 00-19
2. Labor and workmanship shall be covered for no-less than twenty (20) years from date of substantial completion of this work. 3. The Warranty on the Station Cabling and Components shall be a System Warranty and cover the Permanent Link (Communications Outlet to Patch Panel or Block) as defined by the referenced EIA/TIA documents. 4. This Warranty shall be direct from the manufacturer(s) of the cabling and connecting components to the Owner. 3.9 DEMONSTRATION A. Train Owner's maintenance personnel in cable-plant management operations, including changing signal pathways for different workstations, rerouting signals in failed cables, and keeping records of cabling assignments and revisions when extending wiring to establish new workstation outlets. Include training in cabling administration software. END OF SECTION 27 15 00-20
